I stand corrected. This must be "new" for this generation, first I've heard of it. Typically, one of the drive slots has PCIe lanes attached directly to the CPU, and the others all go through the PCH, so this is not a surprise. Though I can't explain why Dell numbered them the way that they did (assuming that this is actually the reason behind what you are experiencing).

Cannot confirm. Have not tried it personally. I have heard multiple stories of users trying 330W in "regular" hardware configurations and it not offering any benefit over 240W at all. But stock configurations are hard to push past 240W power needed just for compute. So what I was going for is something like: if there is any chance that >240W will get you some benefit, you'd have to be using an aftermarket high-power GPU. If the system isn't charging, I doubt that it is the PSU's fault. The system should charge even with a 90W adapter (maybe even less) if it is powered off. I see you have new motherboards on the way to test, but there's also a chance that it could just be the battery going bad?

Oh, I don't take it that far, I just blow them with air from every angle that I can manage. (And mine still developed the rattling, too.)

I do have to remember to clean mine every few months in order to get the fans back to "silent mode" again ...

This is controlled by a mux that sets itself up at boot time. I believe what you are asking for is possible in systems that support NVIDIA's "Advanced Optimus" which can actually "dynamically" change which GPU is driving the laptop display, without a reboot. However, Dell hasn't implemented Advanced Optimus into these workstations.

There is no indication that we are getting such models this year. Nothing has appeared in regulatory databases. Intel didn’t release “business/pro” versions of the HX CPUs for this generation.

I don't have experience with this system, but what you describe here is the exact behavior from the Precision 7770 and 7780. If the built-in display supports VRR but not full GSYNC, then you can only use VRR with the iGPU driving the panel.

You can use a 330W adapter and it will work (any Dell adapter with the right connector on the end), but it is not going to pull the full 330W. Just like how you can plug one of the Precision 240Ws into a Latitude with integrated GPU and it will "work", but it won't pull nearly 240W. Past experiments with this era of systems have shown that it doesn't really give you any "benefit" over 240W. It might be helpful if you are using one of these >100W aftermarket GPU upgrades, if there isn't something in the system that would cap the power going to the card. It would be interesting to have some comparison benchmarks.

I'm still using the 7560 at work. I also started to have rattling fans at certain RPMs. Fortunately, I was just before the three-year warranty cutoff when it started so I just had them ship a new heatsink out. That did take care of it.

Yes, those are the ones. I don't know if you could fit a full fat 980 in (without the "M"), IIRC is it a weird shape and requires an extra power connector. Everything newer than that is eDP only. [Edit] This is the GeForce 980 (no "M").

Any M.2 PCIe Wi-Fi card should work fine. I upgraded my Precision 7530 to Wi-Fi 6 (Intel AX210 card). Just sure the card is PCIe and not CNVi / CNVio.

New Precision systems announced. We have "Pro Precision 5" and "Pro Precision 7", each with a 14" and 16" version. I am guessing that the flagship workstation will be "Pro Precision 9" which is not announced yet. https://www.notebookcheck.net/Dell-unveils-Dell-Pro-Precision-5-Series-14-and-16-with-Intel-Panther-Lake-and-LPCAMM-memory.1251264.0.html https://www.notebookcheck.net/Super-powerful-Dell-Pro-Precision-7-14-and-Pro-Precision-7-16-workstation-laptops-are-now-official.1251730.0.html

Check the GPU shape/dimensions using photos. If it is not the same as a 7560 GPU, you're going to have issues. As far as I know, all 7760 GPUs are the same size, but I am not completely sure about that.

I was referring to M4700/M6700 here. These systems can only use iGPU with an LVDS panel.

See: The 7760 GPU is physically larger and will require physical mods in order to "make it fit".
